SPECIFICATION forming part of Letters Patent No. 410,724, dated September 10, 1889.

Application filed March 23, 1889. Serial No. 304,556. (No model.)

To all whom it may concern: Reference to Fig. 1 will make it apparent Be it known that I, LEVI D. YORK, of that the rolls willproduce an I-beam or girder Portsmouth, in the county of Scioto and State with the web in a horizontal position, and it of Ohio, have invented a certain new and usewill be readily seen that the cylindric portions ful Improvement in Rolling Apparatus, of a of the rolls A A form the web or body of which the following is a specification. said beam orgirder, that the angularportions I will describe an apparatus embodying my a a of said rolls form the inner or opposite improvement, and then point out the novel sides of the flanges of the beam or girder, and features in the claim. that the smaller cylindric portions a a" form [0 In the accompanying drawings, Figure l is the edges of the flanges.

These weights are somewhat heavier than the roll A and its journals and other appurtenances; hence they will always elevate said roll and its appurtenances when the force ordinarily exercised to hold said roll and its appurtenances down shall be relaxed.

Above the journals a a of the roll A are half-boxes a, which serve to resist the upward movement of the roll, and therefore to exert upon the roll the pressure which is req uisite for the rolling operations. The side frames D D are of open construction, so as to constitute housings d. The edges of these half-boxes a are fitted to the edges of the housings d, and are guided by the latter when moved up and down.

Above the boxes a are screws E E These screws extend through the upper portions of the side frames D D above the housings therein, and engage with nuts which are fitted into these portions of the side frames. By rotating these screws in one direction they may be made to force the boxes a downwardly, and by so doing force the roll A and its appurtenances downwardly, so as to re duce the space between this roll and the opposite roll A If the screws are rotated in the reverse direction, they will allow the roll A and its appurtenances to rise and so increase the space between it and its fellow A The upper ends of the screws E E are shown as having affixed to them bevel gearwheels 6 e These bevel gearwheels e11- gage. with bevel gear-wheels e e, affixed to a shaft F, extending transversely to the length of the screws. The shaft F constitutes a driving-shaft for the mechanism employed to effect the adjustment of the roll A and also the adjustment of other parts, as will hereinafter be explained. I have shown the shaft F as provided with a wheel F, that may be operated by hand to 'rotate the shaft. The shaft may, however, if preferred, be combined with means enabling it to be operated by power.

The shaft F is supported in bearings f, which are provided with suitable boxes for receiving the shaft and which are fitted to vertical rods f in such manner that they may slide up and down along said rods. These rodsf are supported on horizontal sliding blocks G G I may remark in passing that these horizontal sliding blocks G G serve to support the rolls B B The shaft obviously is raised and lowered when the bearings a are elevated and lowered. This raising and lowering of the shaft F is provided to enable it to always maintain its relations with the screws E E regardless of change in position of the latter brought about by rotating them for the purpose of adj u sting the upper roll A.

The shaft F is coupled to the screws E E toward and from the rolls A A by coupling-pieces j" (hereshown as consisting .of collars fitting the shaft loosely) and transverse tubular extensions extending over cylindric extensions 6 at the upper ends of the screws above the gear-wheels e 6 The cylindric extensions 6 where they fit within the coupling-pieces, have circumferential grooves. Screws 6, passing through the coupling-pieces and extending into the said circumferential grooves, fasten the coupling-pieces and the screws E E together, while still permitting the screws to rotate. It will be observed that the journal a of the roll A extends considerably beyond the bar a", upon which it rests, and that at the outer extremity it is constructed to interlock with a coupling serving to connect it to a shaft, whereby rotary motion will be imparted to it.

As the shafts which are employed to drive the rolls A A may be of ordinary kind,I have not deemed it necessary to illustrate them, and I shall not further describe them, saving only to add that the shaft which drives the roll A may be supported in such a man ner that it may assume inclined positions to adapt it to the raising and lowering of said roll.

The side frames D D have extending from their outer sides lateral projections (1 01 the side frame D having two parallel and opposite lateral projections d, one near the front edge and one near the rear edge, and the side frame D having similar projections (1 The sliding block D has its inner portion, or, in other words, that portion which is nearest the rolls A A fitted between the two lateral projections cl of the side frame D. The adjacent surfaces of the projections cl and inner portion of the block G are rabbeted and grooved, so as to form shears or ways along which the block G may slide The outer portion of the block G extends beyond the ends of the projections d, and at the extremities has affixed to it, beyond the said projections (1, rods 11 11 These rods H H are secured to the guides O (7 hence, whenever motion is imparted to the blocks G, a corresponding motion will be imparted tothe guides 0 C The sliding block G is constructed like the sliding block G and is fitted to the projections d of the side frame D in a manner similar to that in which the block G is fitted to the projections d of the side frame D. Rods H H are at one end secured to the extremities of the outer portion of the block G beyond the projections 61 of the side frame D and at the other end these rods 1-1 H are secured to the guides C C, so that when the block G is moved the guides C C will be similarly moved.

Thelateral projections d d of the side frames D D are provided with pockets 61 into which are fitted nuts for engaging with screws I I I I. These screws are provided the sliding blocks G F. The shanks of the screws are provided with circumferential grooves. \Vith these grooves engage the forked ends of plates 2", which are secured to the sliding blocks. The screws are thus secured to the sliding blocks, so as to be incapable of longitudinal movement independently of the sliding blocks. Owing to this it will be obvious that when the screws are rotated the nuts will cause them to move longitudinally, and their longitudinal movement will impart a movement to the sliding blocks toward or from the rolls A A according to the direction in which the screws are rotated.

The screws 1 l are provided with bevel gear-wheels F. The gear-wheels engage with bevel gear-wheels i aflixed to a shaft 1 In this manner the screws I I are secured together. In like manner the screws 1' I are provided with bevel gear-wheels engaging with other bevel gear-wheels on a shaft corresponding to the shaft 1, and are thus geared to operate in unison. The pair of screws 1 1 are driven through a shaft J 2 from the shaft F. The screws 1 I are similarly driven through a shaft J from the shaft F. It will be seen, therefore, that the two pairs of screws are driven in unison and correspondingly, and from this it will be obvious that the rolls 3 B and guides O and C and O and G will be moved correspondingly toward or away from the rolls A A The side frames D D have formed in their opposite or adjacent sides recesses d for the accommodation of the guides when they are adjusted as far as they can be adjusted away from each other.

The shaft F is provided at the ends with bevel gear-wheelsj, which engage with bevel gear-wheels j, aflixed to rotate with the shafts J J The gear-wheels 3' have long hubs and are engaged by feathers or splines with the shafts J J hence they may slide along the shafts J J when the shaft F is raised and lowered through the action of the screws E E and yet will rotate the shafts J J The gear-wheels j haye long hubs j", formed with or secured to them, and are engaged with the shaft F by feathers, so that this shaft shall be incapable of rotating without imparting rotary movement to them, and withal so that they can slide lengthwise of the said shaft F. The boxes or bearings f, which receive the shaft F and are free to slide along the rods f, embrace the hubs j of the bevel-wheels j; hence when the sliding blocks G G which carry the rods f, move toward and from the rolls A A the bevelwheels j will be moved correspondingly along the shaft F. The hubs j" of the bevel-wheels j are also embraced by yokes j, and these yokes embrace the hubs 7' of the bevelwheels j. These yokes are so connected with the hubs of the bevel-wheels that there can be no relative movement between the yokes and hubs of the wheels, saving only as regards a rotary movement of the wheels.

These yokes cause the bevcl-whcelsj to slide along the shafts J J when the shaft F is raise d and lowered by the action of the screws E E.

It will be understood that when the shaft F is rotated it will, by operating the screws E E adjust the upper roll A relatively to its fellow A and also adjust the rolls B B and the opposite pairs of guides O and O C laterally with relation to the rolls A A By this means the several rolls and the guides may be adjusted into positions adapting them for successive rollings of any given bar or mass of metal for the purpose of reducing it to a bar, beam, or girder of desired configuration.

At the lower end the shafts J J are provided with bevel gear-wheels j, which are engaged with them by means of keys and engage with and impart motion to the bevel wheels i on the screws 1 1 Around the shanks of the screws 1 1 are collars j These are shown as severally made in two sections secured together by bolts. They are severally provided with sockets j, receiving the ends of the shafts J J These shafts J J are provided near the lower ends, where they enter the sockets, with circumferential grooves, and the sockets are provided with screws 3', which enter the circumferential grooves, thus securing the shafts J J within the sockets, and thereby connecting them with the shanks of the screws 1 1 By means of the connections, which have been just described, for securing the bevel gear-wheelsj in operative engagement with the bevel-wheels 1' it is possible to disconnect the said wheels 3', elevate them and their shafts J J then make adjustments of the screws, which are driven through the shafts J J and afterward restore the connections, so as to make the said screws again operative through the shafts J J This is advantageous, because where a different shaped or sized bar is to be produced the mechanism will be reorganized or specially adapted to the doing of that work and afterward restored to such operative condition that all the adjustments can be effected by the rotation of the Shaft F.

Now a description will be given of the manner in which the rolls B B are supported and how they are adjusted through the adj ustment of the sliding blocks G G Each of these rolls 3 B is shown as having a single journal g, and this is located on the bottom and fits in a block g. The blocks g of the rolls B B rest on the journals a a of the roll A To adapt them the better to do this they are curved on the under side to conform to the circumference of the journals. These blocks are connected by bolts 9 With the sliding blocks G G the block g of the roll B being connected by bolts 9 with the sliding block G, and the block'g of the roll 13 being connected by bolts q with the slid- The rolls B B are not suping block G ported against the metal being rolled bytheir journals g. .These journals are employed for securing the adjustment of the rolls. The rolls are sustained during work by rollers K K There are two rollers K, and they are arranged so as to bear upon the roll B at different points. They are arranged relatively to the roll 13 so that the axis of the roll B and the axes of the two rollers K are in the position of the point of the apices of a triangle. The roll B is sustained by two rollers K arranged with relation to it in the same manner as the rollers K are arranged relatively to the roll B. The rollers K K are supported in the sliding blocks G G These blocks, in the sides which are toward the rolls A A have pockets or recesses g formed in them, and the rollers K K extend into these pockets or recesses. The journals of the rollers K K fit in halfboxes in the edges of the blocks G G above and below the pockets or recesses thereof.

I have shown collars g fitted to the ends of the journals of the rollers K K and connected by rods 9 and nuts g with lugs formed upon the blocks.
